摘要
从理论的角度以高速船的弹性碰撞问题为对象,将船体板架简化为板条梁结构,建立了薄壁梁—刚性墙碰撞模型,分析了其初始条件及边界条件,并对控制方程进行了数值求解。对给定算例进行了计算和结果分析,考虑并讨论了不同初始速度及初始缺陷对碰撞过程的影响。
The elastic impact of high-speed ships is studied theoretically. The hull is simplified into a thin-walled beam. The model of thin-walled beams impacting to the rigid wall is established. The initial conditions and the boundary conditions are analyzed. The control method. Programming and analyzing are performed to an example, ties and initial imperfections on the impacting process are taken int equations are resolved by a numerical and the effects of different initial velocio account and discussed.
